Measurement of Magnetic Field from Electrical Appliances in EEE Classrooms of Southeast University Bangladesh

Abstract

The aim of this survey is to investigate whether the Electromagnetic Fields (EMF) emitted from various air conditioners and switch boards affect the students, faculties and employees. There is a standard threshold value recommended by WHO for both electric and magnetic fields. Electro-Magnetic Field also named Non Ionizing Radiation is emitted from high power transmission lines, computer monitor/video display unit, radio waves of different frequencies, telecommunication, satellite, radar etc. which causes health hazards to living system and environment. There has not been much study performed in Bangladesh. The data were collected from various Computer Science and Engineering (CSE) department labs and classrooms at Southeast University in Dhaka, Bangladesh. Both threshold values of Electric and Magnetic fields were measured for various air conditioners and switchboards. The maximum value of the magnetic field results showed that in many cases the magnetic field radiated from the different sources are greater than the threshold limit, which are the main point of our findings.
